DUMPING DEVICE FOR WAGONS.

SPECIFICATION forming part of Letters Patent No. 509,245, dated November 21, 1893. Application filed July 11, 1893. Serial No. 480,129- (No model.)

To all whom it may concern.-

Be it known that I, OHAELEs H. PEARDON, of Smithshire, in the county of \Varren and State of Illinois, have invented a new and useful Improvement in Dumping Devices for Wagons, of which the following is a full, clear, and exact description.

My invention relates to improvements in means for the elevation of a loaded Wagon and the subsequent dumping discharge of the load; and has forits object, to provide a novel and convenient device, which will afiord reliable means for the elevation of the wagon to a desired height, and its automatic inclination for the discharge of the contents of the wagon body. To this end, my invention consists in the construction and combination of parts, as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of the improved dumping device, and a wagon in position on it. Fig. 2 is a plan view of the dumping device broken away toward the front. Fig. 3 is a rear end view of the dumping platform, and a wagon on it. Fig. 4: is an enlarged partial side view showing features of the improvement; and Fig. 5 is a detached transverse sectional view of a wagon axle, a wheel in part, and a novel detail of construction connected to the axle.

The improved dumping device is designed to facilitate the transfer of material of any kind, that is hauled in bulk in the bed of a wagon or cart, from the wagon to another con veyance that may be a wagon, car or boat, or the place of deposit may be a bin from which the material is to be removed as occasion may require. It is essential for the designated use, that there be provision made for the proper elevation of the loaded wagon, and to this end a framed structure iserected at a point where the dumping operation is to be effected, consisting of two series of spaced stanchions A, that are erected in parallel rows, on suitable foundation, which may be in the form of heavy sills B. The stanchions in each row are suitably graded in height so as to become successively higher from the front to the rear, and on their upper ends the cap pieces 0, of the frame are secured. On the longitudinally extending cap pieces 0, that are sufficiently spaced apart by their supports to afford the required room for a wagon to travel between them, transversely extending planks D, are affixed at their ends, so as to produce a strong road bed, that is upwardly inclined to a height that will adapt the structure for its use as an elevator foraheavily loaded wagon, and in order to add to the stability of the structure inclined braces A, may be secured between the stanchions A and sills B, as indicated in Fig. l, guard rails A, being erected at each side of the track-way.

On the highest portion of the inclined track-way, as the road bed of the described structure is for convenience termed, a trans-' verse shaft or, is journaled by its ends in proper boxes, which shaft forms the support for a platform E, that is given a sufficient length to adapt it to receive and sustain a wagon such as F, on its upper surface.

The platform E, is intended to form an extension of the stationary track-way and have the same degree of inclination when in a normal position, a portion of the flooring of the track-way being omitted where the platform is introduced, so that the latter may be rocked between the cap pieces 0. The point of pivotal support for the platform is so arranged, that its end which is nearest the upper terminal of the track-way, will preponderate in weight over the other end portion, whereby the platform will be caused to normally assume the position shown in Fig. 1, and thus have its transversely planked surface aligned with the planking D.

For the proper support of the adjacent ends of thetrack-way and platform E, said ends are made to rest on the cap-pieces C, directly above two opposite stanchions A. The end of the platform that is nearest to the upper end of the track-way, is detachably secured in connection with the cap-pieces and stanchions mentioned, so as to lock the platform in the same plane with the track-way until released, by mechanism that will be'described. Two similar latch hooks b, are provided, which are pivoted by their lower ends on the sides of the supporting frame of the track-way at opposite points near the upper end of the latter. Each latch hook projects upright, and has its hooked projection sloped on the edge 5 that is nearest to the sloped end of a detent plate 0, that is affixed to the side of the platform E, in a position to adapt it for a latched engagement with the hook of the piece I). which it is opposite, such a connection of to parts being enforced by the springs d.

The latch hooks b, may have their bodies spring-shaped, and thus be sufficiently resilient to latch upon the sloped ends of the detent plates if the lower ends of such I spring latch hooks are affixed to the sides of the track-way supporting frame.

Upon the upper surface of the track-way and platform, two guide rails e, are secured parallel with each other, and also with the side edgesof the parts named. which they are near to. The rails care separated at the point where the platform and track-way lie adjacent when aligned, so as to allow the platform to rock on its pivotal supports, and said rails being equally removed from the edges of the parts they are secured upon, serve to guide the wheels of a wagon F, when the latter is drawn upwardly on the track-way to locate it upon the platform.

Each latch hook I) has a loose connection formed between its upper end and one terminal of a rope or other flexible connection 9,

these ropes of a similar length each having an engagement near their ends that are at- 3 5 tached to the hooks, with a bracket supported loose pulley h, which pulleys are held projected outwardly from the sides of the trackway and have guard loops h, formed on their frame to prevent the rope from displacement.

From the pulleys h, the ropes g, extend rearwardly to opposite points near the outer end of the platform E, where the rear ends of the ropes are affixed to the arms '5 above the points of pivotal support of the latter, said arms be 5 ing loosely secured to similar depending bracketed hangers '6, or equivalent projections from the sides of the platform E, the upper end portions of the arms extending inwardly over the guard rails e, to receive the impinge of the rear Wheels of the wagon F.

The rear end of the platform E, is limited in its downward movement by the guard posts A that are erected on the sills B, at their rear terminals, which rear ends are prefer- 5 5 ably connected by a transverse timber as indicated by a dotted line in Fig. 1, the upper ends of the posts being similarly connected.

Upon the platform E, a buffer frame E, is erected transversely of the platform and near its rear end, the upper cross timber of which frame is designed to receive the impinge of a loaded wagon that may be drawn upon the platform from its front end, and thus check the rearward movement of the wagon.

On the side edges of the platform E, similar railings E are erected that correspond in height and form with the railings A of the track-way, and at their rear ends a cross-bar m, is secured by its ends at a proper height from the flooring of the platform.

A preferred means for propelling the wagon F, up theinclined track-way, from the ground to a proper position on the platform E, consists of a cable G, that may be a rope or chain, the forward end n, of which has asecure connection with the doubled shorter chain G, at its bight, as indicated in Fig. 2. The ends of the chain G, are each provided with a hook 0, to adapt the chain ends for a quick detachable connection with the front axle F, of the wagon F, which is effected by passing said end portions around the axle near the wheels, and latching eachhook upon the body of the chain as shown in Fig. 5, such an attachment being produced when a loaded wagon is to be drawn upwardly on the track-way. From the point n, where the forward end of the cable G, is connected to the doubled chain G',,the cable is extended rearwardly on the track-way, and is caused to engage the grooved periphery of a pulley 1), that is sustained by a bracket frame which is attached to the crossbar m, near its center, from which pulley the cable trends downwardly, to have contact with the grooved edge of another pulley 0", which is supported to rotate on a cross beam of the sills B, and thence the cable is forwardly extended of a suitable .lengthto permit this end portion to be connected to a team of draft animals, or other source of power.

When a loaded wagon is to be elevated and have its load dumped, the rear end of the Wagon is backed toward the foot of the trackway, and the hooks 0, adjusted to. attach the end portions of the draft chain G on the front axle of the wagon, as before mentioned. The wagon tongue if adapted to be lifted, should then be secured in an upwardly inclinedposition by any suitable means, as represented in Fig. 1. Draft force is now applied to the appropriate end of the cable G, which will draw the wagon up the inclined track-way, and on the platform E, the progressive movement being continued until the arms 7 are rocked, the latch books I), released, and the draft of the cable causes the rear wheels of the wagon to impinge the buffer frame E, the shock of such an impact causing the platform to tilt as indicated by dotted lines in Fig. 1, and dump the load from the wagon body, the end gate of which has been previously unfastened so that the jar will drop it and permit a free discharge of the contents of the wagon bed. When the load has been dumped, the strain on the cable G, is slackened, which will permit the heavier front end of the platform E, to descend and be automatically secured by the latching devices as before explained, the gravity of the wagon causing it to descend the track-way, when the chain G, may be released and the vehicle be connected to draft animals for its transportation to a point where it may be again loaded. It will thus be seen that the improved dumping device is automatic in its operation, after a wagon has been placed and connected to a source of power as hereinbefore mentioned, and that the operation of transferring a load from a wagon to another receptacle at the point of discharge that may be above the level of the ground, is speedily and easily effected.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a dumping device, the combination with a track way, of a rocking platform at one end of the track way, latches for locking the platform in position, inwardly projecting pivoted arms, and a connection between the latches and arms, substantially as described.

2. In a dumping device, the combination with a track way, of a rocking platform at one end of the same, spring latches for locking the platform in position, pivoted arms having inwardly projecting ends, guide pulleys, ropes having one end secured to the latches passed around the guide pulleys and their other ends secured to the pivoted arms, substantially as described.

3. The combination with a framed structure, an upwardly inclined track-way thereon, a rocking platform at the top of the track-way, over-weighted at the front end, a latching device detachably holding the platform inclined with the track-way, a buffer frame on the rear of the platform, and abutment posts at the rear of the structure and lower than the point of rocking support for the platform, of a supported cable adapted for attachment to a wagon and a source of power, and by longitudinal movement draw the wagon upon the platform, cause it to trip the latching device, and tilt the platform rearwardly to cause it to strike upon the posts, substantially as described.

4. In a dumping device for wagons, the combination with an upwardly inclined supported trackwvay, and a pivoted platform at the top of the track-way, overweighted atits forward end, of a latching device for the platform, comprising spring-pressed latch hooks pivoted on the sides of the track-way, detent plates secured to the sides of the platform in the path of the hooks, tripping'arms pivoted at the rear of the platform, flexible connections between the hooks and the tripping arms, and a draft cable adapted for attachment'at its ends to a wagon and a source of power, whereby the wagon may be drawn upon the platform and impinged on the tripping arms, substantially as described.
